Uich'on （1055-1101）; one of the major Korean scholar-monks of the mid-Koryo. His major area of expertise was in Hwaom 华严， but he ended up becoming most famous for being a transmitter of the Ch'ont'ae 天台 tradition in Korea. He was one of the Koryo's most famous advocates of Son/Kyo unity. Uich'on was the fourth son of a devout Buddhist king， and entered the sangha at a young age. Like most other early Koryo monks， he began his studies in Buddhism with Hwaom. He later traveled to China， where he studied under a number of leading masters from a variety of lineages， including Ch'an 禅宗， Hua-yen， Vinaya 戒律， Pure Land 净土 and Tiantai. Returning to Korea， Uich'on very actively spread the Ch'ont'ae teaching， believing that it， as a balanced system， provided a viable solution to the heated Son/Kyo debate which surrounded him at the time. Ultimately， however， his negative attitude towards Son undermined his efforts to accommodate Son adherents， and he died fairly young without accomplishing his mission. His main writings are contained in the Taegak kuksa munjip 大觉国师文集， and he is also famous for his histories and catalogues of Buddhist texts， which have been an invaluable source for later scholars.
